Abstract
A planet-carrier for an epicyclic gearing having an annular structure, provided with a coupling portion for being connected to a rotating member or to a static structure in an angularly fixed manner, and a ring that is coaxial to the annular structure along a transmission axis and consists of a plurality of plate-shaped sectors and of a plurality of attachment sectors, alternating with one another about the transmission axis; the plate-shaped sectors lie on a plane orthogonal to the transmission axis and are fixed with respect to pairs of pins, which protrude in opposite directions from the plate-shaped sectors and are adapted to carry respective planet gears; each of the attachment sectors is fastened to the structure by a corresponding pair of arms, which converge with each other towards the ring and are elastically deformable so as to allow a relative movement between the ring and the structure under load.
